If year long tution is around 30,000 can I still get tuition refund or education expnse?

I got my 1098 T form from grad school (full-time student, still in school), however after I filled out all the information that was checked on my form, it came out to be zero. Last year for 2018, I got my $1000, which the amount was around 12900. This time when I got my form the box 1 was around 30,000 which I am guessing combining 3 semesters of the tuition fee. Why can I not get the $1000 refund of the expense...?
